PHOENIX -- Alyssa Thomas had the first 20-point triple-double in WNBA postseason history, and the Phoenix Mercury advanced to the semifinals by eliminating the defending champion New York Liberty 79-73 in Game 3 on Friday night.
Satou Sabally added 23 points and 12 rebounds for the fourth-seeded Mercury, who play at top-seeded Minnesota on Sunday to start the best-of-five semifinal round.
Thomas, who had 11 rebounds and 11 assists, has five of the seven WNBA playoff triple-doubles.
Sami Whitcomb scored 13 points and Kahleah Copper had 12 points and nine rebounds for the Mercury, who had a 49-33 advantage on the boards. DeWanna Bonner had eight rebounds to pass Candace Parker for the most boards in playoff history with 614.
Breanna Stewart, five days after spraining the MCL in her left knee in overtime of a Game 1 win, scored 30 points, including the last 14 in the fourth quarter for the Liberty. Sabrina Ionescu added 22 but the rest of the Liberty struggled.
There were five ties and 13 lead changes through three quarters, which ended with Phoenix on top 60-59, but New York never led in the fourth.
Stewart's three-point play had the Liberty within 65-64 with 6:51 to play. But Thomas had a basket, two assists and a rebound to get her ninth triple-double of this season, as the Mercury surged ahead 72-64 with 5:36 to play.
Stewart made two free throws -- she was 12-of-15 from the line -- to make it 76-73 with 1:10 to play. The Liberty had a turnover and three misses in the last minute and finished 7-of-32 from 3-point range, including 1-for-17 in the second half.
The Mercury led by 12 in the second quarter but with Ionescu scoring 12 points the Liberty cut it to 45-41 at halftime.
